450 Ohm Ladder Line – 18 AWG Solid Copper Wire for Balanced Feedline Systems

Our 450 Ohm ladder line uses 18 AWG solid bare copper conductors and precision-spaced polyethylene webbing to create a low-loss, high-efficiency balanced feedline ideal for HF antenna systems. Ladder line is a favorite among amateur radio operators for its low attenuation and wide bandwidth performance.

Why Choose 450 Ohm Ladder Line?

  • ✅ Low Loss – Excellent for long feedline runs where efficiency is critical
  • ✅ High Impedance – 450 Ohm characteristic impedance for multi-band and balanced HF antennas
  • ✅ 18 AWG Solid Copper – Maximizes conductivity and mechanical durability
  • ✅ Weather-Resistant Webbing – Polyethylene separators withstand outdoor exposure and UV

Best Used For

  • ✅ HF dipoles and doublets fed with balanced line
  • ✅ Multiband antenna systems with antenna tuners
  • ✅ Long, low-loss feedline runs to remote antennas
  • ✅ Homebrew or portable open-wire fed antennas

Specifications

  • ✅ Impedance: 450 Ohms nominal
  • ✅ Conductor: 18 AWG solid bare copper
  • ✅ Conductor Spacing: 0.9" (2.29 cm)
  • ✅ Insulator: UV-resistant polyethylene webbing
  • ✅ Power Handling: Up to 1500W HF (with proper installation)

This 450 Ohm ladder line is trusted by hams who demand high performance and low feedline loss. Available in cut lengths and full spools to match your antenna installation requirements.
